USB 2.0 - Doesn't work (ASUS P4B533-E)

[Rob]

I have been having a terrible time trying to get a USB 2.0
CompactFlash reader to work on my system. I am also
having similar problems with my USB 2.0 externally powered
hub (my card reader is directly plugged into the system--I
have a couple less important devices on my hub).

I am running WinXP Pro SP1 (and I added the post SP1 USB
fix along with essentially all the "Windows Update"
fixes). I also applied the latest Intel Chipset Software
Utility (5.0.2.1003) using the "-usb2" option to add USB2
support for WinXP.

All to no avail.

1) The system continues to complain that I've connected a
high speed device to a low speed port (both for the card
reader and the powered hub).
2) The USB hub doesn't resume life after I put the
computer in sleep mode (I had to hot-plug the USB cable to
liven it up).

When I look at the device manager, it doesn't have any
apparent problems. It is interesting, however, that it
lists 3 "standard" USB controllers and 1 "enhanced" USB
controller (all contain a "USB Root Hub" under them). ALL
of my USB devices claim to be plugged into one of the
3 "standard" USB controllers and the "enhanced" controller
shows 6 open slots.

My ASUS P4B533 has (supposedly) full USB 2.0 support. It
has 6 USB connectors (2 pair onboard; 1 pair via a
connector that is USB 2.0 rated). There are no additional
USB 2.0 connectors that I can find. I have the latest
BIOS (1014).

In the BIOS, I've disabled "legacy USB" support. My
choices for "USB 1.1" are "Disabled" or "3 Controllers" (I
choose 3 controllers, since "Disabled" removes the "USB
2.0" choice. I then chose "Enabled" for USB 2.0 support.
I left the USB HS Reference Voltage at "Medium".

Any thoughts, suggestions, or (best of all) solutions??

Thanks,
....Rob

Uninstall Universal Serial Bus Controllers in Device Manager. Then
reboot PC and let Win XP SP1 detect the USB hardware.

Worked for me with my ASUS P4P800!
